ToL alfwhom it may concern: .Y i

Be it known that we, JAMES J. PARKER, o

Fulton, in the county of Oswego, and TALBOT C. DEXTER, of Pearl River, in the county of Rockland, State of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following,

taken in connection with the accompanying drawings, is a full, clear, and exactdescrip- Iotion.v

This invention relates to the class of paperregistering instruments in which a revolving roller is arranged immediately under the plane of the paper to be registered to receive a frictional hold on said paper, so as to shift the same to its registering position by the.

assistance of a roller over the paper and pressing the same into intimate contact with the subjacent roller.

2o The chief object of this invention is to simplifythe construction of the'V registering instrument without impairing its efficiency; and to that end the invention consists in the novel construction and combination of the constituent parts of the instrumentv as hereinafter described, and set forth in the claims.

In thelannexeddrawings, Figure lis aside elevation of afpaper-registering instrument embodying our invention and showing the 3o same by full lines in position forrreceiving the paper to be registered and in dotted lines in position for shifting the paper to its registering position. Fig. 2 is a side elevation showingsaid,instrument in its position when the paper has arrived at its registering position. Fig. Sis a plan view of said instrument, and Fig. 4 is aside view of a modification of ourinvention. e

Similar letters of reference indicate corre- 4o sponding parts.

YA represents a portion of the main supporting-frame of ,theY machine, on which the registering instrument is employed. The character of said machine is immaterial to our presentinvention,and may be either a paper-folding machine or a paper-feeding machine.

da designate barshupon which the paper is supported in its passage to its requisite position to be operated on by the aforesaid 5o machine. To the top of the frame Aware rigidly se cured the parallel horizontal guides B B,'upon which rides the supporting-bracket C of' the registering instrument. In hangers C' C/ on 55 the under side of the bracket C is journaled the shaft b, to which is fastened the papershifting roller D, which is preferably-provided with a rubber face on its periphery and arranged with the top of its periphery im- 6o mediately under the plane of the bars a a or plane ofthe paper to be registered. Said roller receives rotary motion by means of a gear ZJ', attached to the shaft of said roller andmeshing with a Worm-gear Z2" on a'shaft 65 c, which derives rotary motion from the actuating mechanism of the machine to ,which the registering instrument is connected. The means for transmitting motion to the shaft c necessarily varies with the character 7o of the aforesaid machine and readily suggest themselves to a'mechanic familiar with such lclasses of machines.

'In bearings c' c. on the top of the bracket C is pivoted the vertically-movable arm E, to the free end of whichis pivoted Ythe paperdepressing roller D', whichr intermittently pressesthe paper into intimate contact-With the revolving lower roller D, whereby the paper is shifted to its registering position. 8o Thus far the instrument is organized similar to the registering devices shown and described in the United States Letters .Patent No; 528,657, granted to Talbot O. Dexter .on the 5th day of-November`,vl894.

Our present improvements consist inthe mechanisms for automatically lifting the paper-depressing roller D' at the proper times, irst, to-allow the paper to enter between the rollers, and, secondly, to release the pa- 9o rper after it has been moved to its registering position. To produce said actions 'of @the paper-depressing roller in a simple and reliable manner, we employ mechanism for transmitting motion from the shaft of the roller D to the arm E to intermittently lift the same.4 For this purpose we prefer to attach to the shaft of the paper-shifting roller the machine.

D a cam d and fulcrum on the pivot-pin a' of the arm E the lever I, to the free end of which is pivoted a roller cZ, by which said lever bears on the periphery of the cam d and is thus intermittently rocked. Over the said lever, preferably near the fulcrum thereof, is a suitable bearing on the arm E, so as to cause the lever to lift said arm by the upward movement imparted to the lever by the cam d. In order to permit the said lifting of the arm to be regulated, we employ an adjustable bearing on said arm, preferably of the form of a set-screw e, adj ustably connected to a screw-threaded eye e', formed on the arm, which screw can be turned to cause it to project to a greater or less distance beneath the arm and engage the lug I', formed on the lever I. The said lever I lifts the roller D' to the position shown by full lines in Fig. l of the drawings, in which position it is heldy during the feeding of the paper to its requisite position for being registered in The, cam d is so shaped as to allow the arm E to descend and cause the roller D to press uponthe paper as soon as it has arrivedv at itspositio'n for'being registered. The frictional hold of the lower roller D then shifts the paper to its registering position. To arrest said movement of the paper as soon as registered and release the registered paper, so as to allow it to bev drawn from between the two rollers D D', we employ a suitable pry actuated by the shifting paper and lifting the arm E. For this purpose we prefer to pivot a supplemental roller f to the bracket C or other suitable stationary support back of the paper-shifting roller D, the top of which supplemental roller is in the same plane with that of the roller D. Directly over this supplemental roller is a companion supplemental roller f', pivoted to the arm Il, and in front of the two rollers f f is a iinger g, pivoted to the bracket C andI having its free end in the path of the shifting paper and provided with a tongue g', projecting from it toward the bite of said rollers. A spring h serves to draw the linger from the rollers, and a stop 71 limits said withdrawal. During the movement imparted to the paper by the roller D the edge of said paper is forced against'the free end of the finger g, which is thereby tilted on its pivot and caused to push the tongue g' into the bite of the rollers f f', so as to lift the arm E, as represented in Fig. 2 of the drawings. To facilitate the entrance of said tongue between the rollers, we attach to the shafts of the roller f and roller D', respectively, the gears Q1 and i, and pivot an intermediate gear j to the side of the arm E. By means of said gears motion is transmitted from the roller D to the roller f during the shifting of the paper to the finger g.

The pinching of the revolving roller f upon the end of the tongue g draws the latter between the two rollers f f sufficiently to lift the arm E, which then immediately deprives the roller D of further movement, and consequently the motion of the roller f is also arrested. The tongue g is retained between the rollers while the registered paper is removed from the registering instrument. rlhe cam d next lifts the arm E still higher by means of the lever I and thereby releases the tongue g from the bite of the rollers ff and allows said tongue to be restored to its normal position by force of the spring h. We do not, however, limit ourselves to the use of the mechanical finger g, inasmuch as it can be'dispensed with in case the paper is of sufiicient thickness to lift the arm E to the requisite height by allowing the edge of the paper to enter between the rollers ff', as represented in Fig. 4 of the drawings.

What we claim as our invention is l. A paper-registerin g instrument comprising a roller disposed to shift the paper toward its registering position, a depressor movable to and from said roller to temporarily press the paper into frictional contact therewith and thereby shift thepaper, and a pry actuated by the shifting paper and lifting the de pressor from the roller and thereby arrest the movement of the paper.
